Okay - if you're slinking, so am I 'cause I can do the Vulcan sign with both hands WHILE curling the edges of my tongue

That is so easy! (to anyone yet to try this) I've heard that curling your tongue is genetic, so if you can't do that it's hopeless. It also seems that some people can't do the vulcan sign. I have no explanation to that.
